Abstract

169,692. Beth Maschinenfabrik, W. F. L. April 30, 1920, [Convention date]. Filtering.-In a filter having a throttle valve a for changing the air current during the cleaning of the filter, and a separate device f for closing the inlet of fresh air for the cleaning, the closing device f is displaceably mounted in relation to the rod e controlling the throttle valve and is pressed against the fresh air inlet k by a spring m abutting on the rod. As shown, the rod passes through the closing device which is formed as a cover, and an adjustable stop g on the rod, which passes through the cover, is brought against the cover and opens the inlet when the throttle valve is reversed.
